Specification of Letters Patent.

Patented Feb. 9, 1915..

To all whom it may concern:

Be it known that I, JULIUS HAVAS, a subject of the King of Hungary,residing at Sarbogard, Austria-Hungary, have invented certain new anduseful Improvements in Plowing Mechanism, of which the following is aspecification.

This invention relates to an apparatus for mechanical plowing, which onthe one hand makes it possible to use any self-propelled engine forplowing, and on the other hand insures favorable distribution of forcesand a better utilization of the parts subjected to heavy loads.

A construction according to this invention is illustrated, by way ofexample, in the accompanying drawing in which- Figure 1 shows in planthe cable drum for moving the pulley truck, Fig. 2 shows the cable drumtruck attached behind the engine, Fig. 3 shows on a larger scale acrosssection on the line 3 3= of Fig. 3. Fig. 3 shows the pulley truck,while Fig. 4 shows diagrammatically the apparatus in operation. 7

The apparatus according to this invention comprises the followingparts: 1. Any selfpropelled engine arranged in such a manner that itswinding drum can be reversed. 2. A cable drum truck attached to theengine (Fig. 1). 3. A pulley truck (Fig. 3). 4. A guide pulley. 5.Abalance-plow. 6. Awire cable driving the plow, and 7. A wire cablepulling the pulley truck.

The cable drum 0 pulling the pulley truck, can be arranged either underor in front of the engine (Fig'. 1) but the drum a must be capable ofbeing driven from the main shaft of the engine. The drum a is mountedloosely on a shaft 6 and drives the cable drum 0 only when, on the chaincontrolled from the drivers seat being released, the bell crank lever eallows the j aws g g of a clutch, controlled by a spring f, to come intoengagement. The cable drum then winds the cable h pulling the pulleytruck and passing over a guide roller 2' which, for the purpose ofinsuring uniform winding, is connected to a device which will now bedescribed.

On the spindle of the cable drum is mounted a toothed bevel wheel 11.engaging with a toothed bevel wheel 01. The latter drives by means of aspindle 0 the worm is which, during one revolution of the spindle of thecable drum also makes one revolution and turns a toothed wheel Z to theextent of one B B gether by a rod C which can be reciprocated tooth. Thetoothed wheel Z has twice as many teeth as the number of windings whichcan be arranged side by side in the longitudinal direction on the drum.When the spindle of the cable drum has made half as many revolutions asthe number of teeth of the toothed wheel Z, the toothed wheel Z makeshalf a revolution, and the rod 92? carrying the roller 2', is moved inthe direction of the axis of the cable drum to the extent of the lengthof the cable drum. At the second half revolution of the toothed wheel Z,the roller is again moved toward the other end of the cable drum. Inthat. way, a uniform winding of the cable is insured.

The cable drum truck (Fig. 2) is attached, in working, by means of twoiron bars N directly behind the engine. so that it cannot alter itsposition relatively to the engine. The cable drums are driven from theengine by means of belts, chains or the like. The pulley (1. drivesthe'spindle (1 only when, on a chain connected to a bell crank lever Lbeing released, a spring F brings into engagement with each other thejaws b b of a clutch or coupling. At other times the of the coupling arebrought into engagement with the jaws i by means of the levers The saidlevers are connected tofrom the drivers seat by any desired means. Thedevice for throwing the drums in or out of gear is arranged in such amanner that the jaws of only one coupling can be in engagement with eachother at a time, so that only one cable drum is driven at a time. Thesaid cable drum winds the cable, while the other drum rotates idly, andis moved by the unwound. inoperative, cable.

Uniform winding of the wire cable on the drum is insured bv thefollowing arrangement: On the main shaft is mounted a bevel wheel Kdriving a bevel wheel M mounted on the same spindle with a toothed wheelM The latter wheel drives by means of toothed wheels M M a toothed wheel'm. which drives a worm 1' provided on the same spindle. This worm ateach revolution rotates the toothed wheel a to the extent' of one toothand the said toothed wheel movcsthe driving rod u by means ofthe rod t.On the rodu, are mounted rollers :10 92 which guide the cable 9 drivingthe plow. The engine is mounted on four wheels.

The pulley truck (Fig. 3) comprises a frame consisting of longitudinalmembers 3 y and transverse members 7"? f Between the superposedlongitudinal'members y? y 1s left an opening large enough for thereception of a pulley T secured to a spindle d..

Over the said pulley passes theindirectly working cable 9 which israised into the plane of the pulley T by guide rollers E 13 mounted onthe longitudinal member y, whereby any slipping of the cable out of theguide pulley is prevented.

F or the purpose of increasing the stab1l1ty of the pulley truck, theouter road wheels 0 O are made about 40 cm. wide, and hollow, so thatthey can be filled, before starting work, with water or some othereasily removable material, in order to 1ncrease their weight. In orderto prevent the vehicle from slipping in the direction of the cabletraction, the inner road wheels 0'', 0*

are provided with detachable annular steel flanges I 1 the said flangesbeing secured I to the wheels by hooks K When not working, in transport,the water can be ,discharged from the outer wheels, while the flanges I1 after turning the hooks K rotatably mounted on the same, can beremoved or raised so that they do not touch the ground.

The advance of the pulley truck during working is effected by means ofthe cable h -passlng over a guide roller H. The only alteratlon of' theplow which is required consists merely in arranglng next to the roadwheel running on the ground which has not been yet plowed, a guidepulley H (Ifig. 4) used for guiding the indirectly working cable.

The working with the new apparatus can be seen in Fig. l. ,The plow isworK ngfor instance on a plane representing an irregular rectangle. Atone edge stands the pulley .truck, at the other edge the self-propelledengine to which is connected'the drum truck and toathe front end ofwhich is secured the drurndewice for pulling forward the pulley truck bymeans of the cable 72.. According to Fig. 4:, the cable drum A isworking and drawing the plow, toward itself y means of the cable 9passing around the ulley T of the pulley truck, while the wire cable isbeing unwound from the loose cable drum A.
